    Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
    \n
    I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
    \n
    I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
    \n
    EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
    \n
    While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
    \n
    rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
    \n
    Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
    \n
    Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
    \n
    I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
    \n
    I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
    \n
    EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
    \n
    While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
    \n
    rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
    \n
    Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
    \n
    Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n

    +url: null
    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    +url: null
    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n

At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    +url: null
    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    +url: null
    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    +url: null
    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    Based on this [thread](https://serverfault.com/questions/569354/freenas-do-i-need-1gb-per-tb-of-usable-storage-or-1gb-of-memory-per-tb-of-phys) it’s the deduplication that requires a lot of RAM.\n

    Edit: from my understand the pool shouldn’t become inaccessible tho and only get slow. So there might be another issue.\n

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    +url: null
    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    +url: null
    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    Just to make sure. Are you copying to your ZFS pool directory or a dataset? Check to male sure your paths are correct.\n

    Push vs pull shouldn’t matter but I’ve always done push.\n

    If your zpool is not accessible anymore after a transfer then there is a low-level problem here as it shouldn’t just disappear.\n

    I would installe tmux on your ZFS system and have a window with htop running, dmesg, and zpool status running to check your system while you copy files. Something that severe should become self evedent pretty quickly.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    +url: null
    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    +url: null

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    +url: null
    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    +url: null
    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    > kill -9\n
    \n

    +url: null
    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

    > kill -9\n

    Just tested, thanks for the suggestion! It killed a few instances of `rsync`, but there are two apparently stuck open. I issued `reboot` and the system seemed to hang while waiting for `rsync` to be killed and failed to unmount the zpool.\n

    +body: """
      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

      Hey fellow Selfhosters! I need some help, I think, and searching isn’t yielding what I’m hoping for.\n
      \n
      I recently built a new NAS for my network with 4x 18TB drives in a ZFS raidz1 pool. I previously have been using an external USB 12TB harddrive attached to a different machine.\n
      \n
      I’ve been attempting to use rsync to get the 12TB drive copied over to the new pool and things go great for the first 30-45 minutes. At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.

At that point, the current copy speed diminishes and 4 current files in progress sit at 100% done. Eventually, I’ve had to reboot the machine, because the zpool doesn’t appear accessible any longer. After reboot, the pool appears fine, no faults, and I can resume rsync for a while.\n
      \n
      EDIT: Of note, the rsync process seems to stall and I can’t get it to respect SIGINT or Ctrl+C. I can SSH in separately and running `zpool status` hangs with no output.\n
      \n
      While the workaround seems to be partially successful, the point of using rsync is to make it fairly hands-free and it’s been a week long process to copy the 3TB that I have now. I don’t think my zpool should be disappearing like that! Makes me nervous about the long-term viability. I don’t think I’m ready to drop down on Unraid.\n
      \n
      rsync is being initiated from the NAS to copy from the old server, am I better off “pushing” than “pulling”? I can’t imagine it’d make much difference.\n
      \n
      Could my drives be bad? How could I tell? They’re attached to a 10 port SATA card, could that be defective? How would I tell?\n
      \n
      Thanks for any help! I’ve dabbled in linux for a long time, but I’m far from proficient, so I don’t really know the intricacies of dmesg et al.
